No FontFamily element found – .NET update incompatibility

[JakubH]

We use PlasticSCM 6.0.16.1765 on Microsoft Windows 7 SP1, and recently there is a problem with Microsoft .NET Framework 4.7.1 update KB 4055002. When this update is installed, Plastic won't show any views with error message saying: No FontFamily element found in FontFamilyCollection that matches current OS or greater: Windows7SP1.

For more information see https://support.microsoft.com/en-us/help/4055002/description-of-the-security-and-quality-rollup-for-the-net-framework-4 > Known issues in this update

For workarounds see https://support.microsoft.com/en-us/help/4074906/typeinitializationexception-or-fileformatexception-error-in-wpf-apps-t

Maybe this is something PlasticSCM team can fix in next release.

Hi,

We use some external controls that are also affected by the bug so a fix on our side is not easy. Microsoft has just announced  that the fix is comming soon. Meantime, they propose a few workarounds:
